Calderan Fissure

The Calderan Fissure is a hydrogeological formation consisting of a collection of at least 300 concentrated perpetually erupting fountain geysers. The constant geological activity created a split in the sea floor between the Blue Sea and the Calderan Sea.

The Calderan Fissure also refers to the underwater land formation which results in the high sea floor of the Calderan Sea and the relatively lower sea floor of the Blue Sea. Blue Sea water is essentially runoff from the Calderan Sea. The split in the two seas combined with the current of water flow from the Calderan to the Blue sea creates the Calderan Rapids.

The Calderan Fissure runs along a 50m line from the northern shore of Groftlan to the northern Eyrsan crest.

The cause of the phenomenon is unconfirmed, but scholars believe that the volcanic activity which more than likely created the Eyrsan continent is still active, and the overrun of the Vallosi, Calderan and Blue seas over th Eyrsan crest constantly feed back into a series of subterranean rivers, leading back to the Eyrsan Core. The Calderan Fissure is often seen as evidence supporting the Continental Core Theory.
